Sitecore ECM Unable to remove variant not created in default language

Unable to remove message variant using Sitecore Email Campaign Manager when variant has been not created in default language.

Steps to reproduce :-

  1. Create new message in ECM
  2. Proceed to message step. Ensure language is not EN default language.
  3. Click action drop down to add variant.
  4. On variant B Click action drop down select remove variant.

The page reloads but variant still exists, I had to create a version in the default language EN prior to deleting the selected variant.

This issue was found using Sitecore with 7.1 and Email Campaign Manager 2.1 140214 it was confirmed as a bug via Sitecore support ticket number 434146 and the workaround above was suggested until this gets resolved in the product.
